Description

June 13, 1939. R. JOHNSON DUST REMOVING APPARATUS Filed May 28, 1938 2 Sheets-Sheet l June 13, 1939. R. JOHNSON DUST REMOVING APPARATUS Filed May 28, 1958 2 Sheets-Sheet 2 Patented June 13, 1939 DUST REMOVING APPARATUS Eric R. Johnson, Maiden, Mass assignor to Carl F. Berg, Boston, Mass.
Application May 28, 1938, Serial No. 210,604
2 Claims.
The cutting and carving of stone creates'a fine stone dust which floats around in the air in shops where such work is done. The workmen inhale this dust in large amounts and as a result their health soon is injured. The length of life of such workmen is considerably below average. In order to overcome these difllculties it is necessaryv to conduct this fine dust directly from the points where it is created to the exterior of the work shop. Apparatus provided for this purpose, heretofore, has been very expensive to install and has been so difiicult to use that the workmen did not wish to bother with it and preferred to take their chances with the consequences resulting from inhaling the dust.
It is the object of the present invention to provide an apparatus for overcoming the above difficulties and which is inexpensive to build and install and convenient to use.
The invention will be more clearly understood from the following description in conjunction with the accompanying drawings, in which:
Fig. 1 is an elevational view of an apparatus embodying the invention;
Fig. 2 is aplan view of the same; and
Fig. 3 is a detail sectional elevational view of a portion of the apparatus.
Before explaining in detail the present invention, it is to be understood that the invention is not limited in its application to the details of construction and arrangement 01' parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practised or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention beyond the terms of the several claims hereto appended as considered in view of the prior art and the requirements thereof. n
One embodiment of the invention is illustrated in the accompanying drawings and comprises a frame l0, secured as by clamps 3 in raised position upon a stationary portion of a building, such as a pillar Ii. A rotary blower or air pump i2 driven by a motor I3 is suitably mounted upon the frame in. A vertical shait l5 secured in the frame ill supports a member it having a stationary portion l1 and a rotatable portion IS. The stationary portion i1 is provided with an extension I! connected to the inlet of the blower i2, ,as by bolts 23. An opening is provideclnear the lower end of the conduit portion i3 and is normally closed by a cover plate 23.
A conduit 33 having conduit portions 3|, 32 and 33 is connected to the rotatable member l3 through one end of the conduit portion 3|. The conduit portion II is provided with a down-turned portion 34 which receives the up-turned portion 35 of conduit portion 32. The other end of the conduit portion 32 is turned down and slidably receives the up-turned portion 36 of the conduit portion 33. The conduit portion 3i is supported by a tie rod 31 having one end rotatably engaging the shaft I5 and its other end secured to a link 33 surrounding the conduit portion 3!.
A rod 40 extends through the portion of the conduit 30 formed by the down-turned portion 34 of conduit portion 3i and the up-turned portion 35 of conduit portion 32. One end of the rod 40 is positioned in a tubular projection 4i extending from the wall of the conduit portion 3| and is fixed therein by a pin 42. A sleeve 43 surrounds the rod 40 near its other end and is fixed, as by welding, in a tubular projection 44 extending from the wall of the conduit portion 32. The rod 40 passes through the sleeve 43 and projection 44 and is provided with a pair of rollers 45 bearing against the outer end of the projection 44. A support 46 in the form of a collar fits snugly around the rod '40 and engages the inner wall of the conduit portion 3| near the end of the down-turned portion 34 thereof.
A bracket 50 is fixed upon the conduit portion 32 and supports a pulley 5| for receiving a chain 52. The chain 52 extends through the vertically extending portions of the conduit portions 32 and 33 and is secured at one end 53 to the conduit portion 33. The chain 52 passes over the pulley SI and down through openings 54 in each of the spaced brackets 55 which are connected by a rod 53. The rod 53 passes through an opening 29 in a lever 51 one end of which is fixed upon the chain 32.
It will be apparent from the above description that the conduit 30 as a whole is rotatable about the rod l5 and that the conduit portions 32 and Furthermore, the open end of the endoithe conduit flisheldin itsadlustedposition by the action of the weight 0! the conduit portion 83 upon the chain which causes the lever I! to assume the inclined position as shown in Pig. 1 whereupon the sides oi the opening Il-in theleverllbindagainsttherodll.
I claim: I 1. In a dust removing apparatus, in combination, an air pump, a conduit of substantially uniform diameter having one end open to receive duit portion and fixed to the other conduit portion, and a sleeve surrounding said rod and fixed to said rotatable conduit portion.
2. In a dust removing apparatus, in combination, an air pump, a conduit oi substantialLv uniform diameter having one end open to receive dust and having a connection at its other end to the inlet of said pump, said conduit having spaced curved parts between its ends and comprising two parts so that one portion may be rotated relative to the other portionv to permit the open end ot said conduit to be'positioned adiacent the source 91 dust, a rod providing a bearing for separate portions connected between said curved 1o rotatably supporting said rotatable conduit por- 15 tion and fixed to the other conduit portion, and rollers carried by said rod and engaging said rotatahle conduit portion.
